This specifies relayed service's forwarding address.
For entries with iphelperService equal to iphelperBootp(1):
This object can either be set to a distinct IP address (e.g. the address
of a server), to an IP broadcast address or a VLAN. A value
of 0.0.0.0 indicates that no forwarding address is being used.
For entries with iphelperService not equal to ipHelperBootp(1),
this object is not settable.

This specifies a Vlan to which the service is to be forwarded.
For entries with iphelperService equal to iphelperBootp(1),
a value of 0 indicates that no vlan is being used.
For entries with iphelperService not equal to ipHelperBootp(1),
only non-zero values may be specified.

This keeps track of the number of packets dropped due to DHCP packet with giaddr
field not equal to zero and Relay Agent Information option is present and also the
Relay Agent Information Policy is set to DROP.

This sets the BOOTP/DHCP relay's forwarding delay and
is only used by the BOOTP/DHCP service. For other services
it is ignored.It is typically set as seconds, but the value is totally
client dependent.This relay will not forward frames until client
frames have 'secs' field set to atleast the value
iphelperForwDelay.

This sets the BOOTP/DHCP relay's maximum hops
forwarding limit and is only used by the BOOTP/DHCP service. For
other services it is ignored. If a frame arrives with hopcount greater than
or equal to iphelperMaxHops, it will be dropped.

This is only significant for the BOOTP/DHCP service. It allows the relay
to forward DHCP requests only when they are issued by an Authenticated Vlan
client.Needed to prevent having multiple relays enabled on the same vlan.
Default value is standard

This is only significant for the BOOTP/DHCP service. It allows the user to
enable or disable the functionality of the relay to get an IP address at the
time of system boot-up and assign that IP address as the router IP of the
default VLAN. Default option is Disable.

This is only significant for the BOOTP/DHCP service. It allows the user to
select the packet format with the choices of BOOTP and DHCP to be used to get
an IP address at the time of system boot-up.
Default option is DHCP

A list of services being forwarded with their associated ports.
An entry in this table is allowed only for the services listed below:
iphelperBootp
iphelperNbnsNbdd
iphelperNbdd
iphelperDns
iphelperTacacs
iphelperTftp
iphelperNtp

A list of services being forwarded with their associated ports.
An entry in this table is allowed only for those services
NOT using one of the following well-known ports:
53 - DNS
65 - TACACS
67 - BOOTP/DHCP
68 - BOOTP/DHCP
69 - TFTP
123 - NTP
137 - NBNS
138 - NBDD

This is only significant for the BOOTP/DHCP service. It allows the user to
enable or disable the functionality of inserting the relay agent information
option to the DHCP option field according to RFC 3046.

This is only significant for the BOOTP/DHCP service. It allows the user to
select the policy of either drop, keep or replace the relay agent information
option if it is already present in the DHCP packet.

The DHCP Option-82 data insertion status. Default value
is enabled, which means once the VLAN is enabled for DHCP
snooping, the Option-82 field will be inserted in the DHCP
packets between the Relay Agent and the DHCP Server, on all
the ports belong to the VLAN.

The DHCP Snooping MAC Address verification status. Default value
is enabled. Once enabled, for all the incoming DHCP traffic to
those DHCP Snooping enabled vlan port, it compares the source MAC
address and the client Hardware Address in the DHCP packet. If mismatch,
the packet will be dropped.

The DHCP Snooping Traffic Suppression status. Default value
is disabled. Once enabled, for all the incoming DHCP traffic to
those DHCP Snooping enabled vlan port will not be flooded throughout
the VLAN. The usage of UDP/DHCP Relay Agent will be enforced. Traffic
will always be forwarded to CPU.

The DHCP Snooping's VLAN port's trust mode. Default value
is client-only, which means once the VLAN is enabled for DHCP
snooping, the vlan ports only allow DHCP client packets. Blocked
means all DHCP traffic is block on the port. Trusted means all
DHCP traffic is allowed on the port

This keeps track of the number of packets dropped due to receiving
an DHCP Relase or DHCP Decline message that contains a MAC address in the
DHCP snooping binding table, but the interface information in the binding
table does not match the interface on which the message was received.

The DHCP Option-82 data insertion status at switch level.
Default value is enabled, the Option-82 field will be inserted in the DHCP
packets between the Relay Agent and the DHCP Server, on all
the ports belong to the switch.

The DHCP Snooping MAC Address verification status at switch level.
Default value is enabled. Once enabled, for all the incoming DHCP traffic to
the port, it compares the source MAC address and the client Hardware
Address in the DHCP packet. If mismatch, the packet will be dropped.

The DHCP Snooping Traffic Suppression status at switch level. Default value
is disabled. Once enabled, for all the incoming DHCP traffic to
the ports will not be flooded The usage of UDP/DHCP Relay Agent will be
enforced. DHCP Traffic will always be forwarded to CPU.

This object specifies if the capability of building the DHCP Snooping
Binding Table/Database is enable or not. By default, it is enabled.
It is applicable for both switch-level or vlan-level DHCP Snooping.
